The brutal and sadistic crimes perpetrated by members of the 'Manson family' on his order shocked and horrified the nation.

Sharon Tate was a rising star of the film world who was murdered by Manson family members Tex Watson, Susan Atkins and Patricia Krenwinkel when she was 8 and a half months pregnant in 1969 .

Manson had ordered his family members to slaughter 26-year-old Tate, and three of her friends at her home above Beverly Hills.

Despite the actress pleading for her life and that of her unborn son's the evil killers showed her no remorse and she was stabbed 16 times.

Susan Atkins said she told Sharon as she begged for her life, 'woman, I have no mercy for you' before stabbing her in the stomach.

Stephen Parent was a fifth unfortunate victim that night. The 18-year-old had driven to the property to see if caretaker William Garreston wanted to buy his AM/FM Clock radio, and had stayed on for a beer at the guest house.

Watson aimed a 22-caliber revolver at him when he wound down the window at the electric gate as he left as the youth begged him not to shoot.

The murderer then lunged at Stephen with a knife before shooting him four times.

Manson family member Linda Kasabian was also present on the night of the Tate murders but was found to have had no involvement in the actual killings and was granted immunity in return for her prosecution testimony

Following Manson’s instructions to leave a ‘witchy’ sign that might implicate the Black Panthers, one of his female assassins wrote ‘Pig’ in Tate’s blood on the front door.

The following night the Family butchered small business owners Leno and Rosemary La Bianca, in their home in Los Angeles.

After Manson tied them up and left, they, too, were frenziedly stabbed to death. Their murderers wrote ‘Kill the Pigs’ in blood on a wall, and even carved ‘War’ on Leno LaBianca’s torso.

The murders were carried out in upscale, mostly white neighborhoods of Los Angeles in order to blame the crimes on African Americans, in the hope of sparking what he termed a 'Helter Skelter' race war.

Manson was also later convicted of the slayings of musician Gary Hinman and stuntman Donald 'Shorty' Shea.

During the trial he was convicted of leading a cult in which disaffected young people living in a commune followed his orders and were ultimately turned into killers.

In the end, Manson was convicted of nine counts of murder (including two men who were killed separately) and sentenced to death. However, California ended capital punishment a year later, at which point his sentence was commuted to life.
